compatible with webkit and will allow for easy externalization of strings. One byte strings are retained for pure ASCII strings. (The language specification was changed recently to reflect this as follows "A string is a sequence of UTF-16 code units"). - Remove four byte string class and all references to it. - Rename some of the string functions in Dart API to make them consistent and better describe the underlying functionality Dart_NewString => Dart_NewStringFromCString Dart_NewString8 => Dart_NewStringFromUTF8 Dart_NewString16 => Dart_NewStringFromUTF16 Dart_NewString32 => Dart_NewStringFromUTF32 Dart_NewExternalString8 => Dart_NewExternalUTF8String Dart_NewExternalString16 => Dart_NewExternalUTF16String Dart_NewExternalString32 => Dart_NewExternalUTF32String Dart_StringGet8 => Dart_StringToUTF8 Dart_StringGet16 => Dart_StringToUTF16 Dart_StringToCString => Dart_StringToCString Dart_IsString8 => Removed Dart_IsString16 -> Removed Dart_StringToBytes -> Removed Dart_StringGet32 -> Removed Review URL: https://codereview.chromium.org//11318018 git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@14357 260f80e4-7a28-3924-810f-c04153c831b5
